Struts JSP XML Web Apache

if struts2-spring-plugin-2.0.9.jar is in lib ,we must config the web.xml and application.xml.

The flowing is the simple test code.

HelloWorld.java:

package example;

import com.opensymphony.xwork2.ActionSupport;

public class HelloWorld extends ActionSupport {

public static final String MESSAGE="HELLO STRUTS STARTING";
@Override
public String execute() throws Exception {
  // TODO Auto-generated method stub
  setMessage(MESSAGE);
  return SUCCESS;
}
public String message;
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}

}

hello.jsp:

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta. http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<h2><s:property value="message"/></h2>
</body>
</html>

struts.xml:

<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">
    <struts>
    <package name="stute" extends="struts-default">
      <action name="HelloWorld" class="example.HelloWorld">
       <result>/Hello.jsp</result>
      </action>
    </package>
    </struts>

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<display-name>
strute</display-name>
<filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>

  <welcome-file>default.jsp</welcome-file>
</welcome-file-list>
</web-app>
